DETAILED DESCRIPTION Overview

This disclosure relates to, among other things, devices, systems, methods, computer-readable media, techniques, and methodologies for transitioning user interfaces on an electronic display operatively coupled to a content streaming device for various voice-based functions. User interfaces of the disclosure may indicate to a user a manner in which a voice input or voice data is being or has been processed, as well as information related to a stage of processing of voice data, post-processing information, such as search results or desired information, and the like. Embodiments of the disclosure may generate smooth transitions between various user interfaces irrespective of whether voice input is, for example, a voice command, a voice search, a voice query or verbal request for information, and the like. Users may determine, based at least in part on user interfaces of the disclosure, an operational mode of a device, a processing stage of a device or system, information related to a voice query, and other information. For example, embodiments of the disclosure may include graphical user interfaces (GUIs) designed to communicate that voice input is being received or detected, how voice data will be processed (e.g., as a voice search or verbal query, etc.), results of voice data processing (e.g., search results, requested information such as news or weather, etc.), and other information.

Embodiments of the disclosure may facilitate dynamic voice search transitioning, such that users may identify voice data information from a user interface at an electronic display. Users may consume content on a content providing device or display device, including, but not limited to, a viewing device such as a television, a laptop computer, a tablet, a computer monitor, or the like, and/or devices configured to provide audio content, such as a speaker-type device, including, but not limited to, music, audio books, machine voice responses, spoken text, and/or any other type of audio output. In certain example embodiments, a content streaming device may be configured to communicate with a display device, such as a television. Content streaming devices may be media streaming or media output devices configured to facilitate streaming of remotely stored content and/or presentation of locally stored content.

In certain example embodiments, a user may interact with a content steaming device by providing analog sound input (e.g., voice) to a remote control or other device (e.g., smartphone, etc.) coupled to the content streaming device. The remote control may generate digital voice data representative of the analog sound input and send the voice data to the content streaming device over a wired or wireless communication protocol. The content streaming device may receive the voice data and may generate one or more user interfaces for presentation on a display device, such as a television, that is in communication with the content streaming device. The content streaming device may also send the voice data to one or more remote servers for processing of the voice data to determine a meaning of the sound input, in one example.

The content streaming device may determine whether the voice data includes a trigger word. A trigger word may indicate that the voice data includes a certain type of request and/or is to be processed in a specific manner. For example, a trigger word may be “Alexa” and may indicate that the voice data includes a verbal query and/or that the voice data is to be processed as a verbal query as opposed to, for example, a search request. In some embodiments, the content streaming device may receive an indication of whether the voice data included a trigger word from the one or more remote servers, rather than making the determination at the content streaming device. In certain implementations, the content streaming device may have an expression detector that analyzes an audio signal produced by a microphone of the remote control to detect the wakeword, which generally may be a predefined word, phrase, or other sound. Such an expression detector may be implemented using keyword spotting technology, as an example. A keyword spotter is a functional component or algorithm that evaluates an audio signal to detect the presence a predefined word or expression in the audio signal. Rather than producing a transcription of the words of the speech, a keyword spotter generates a true/false output to indicate whether or not the predefined word or expression was represented in the audio signal.

In certain embodiments, an expression detector of an audio device, content streaming device, and/or remote control may be configured to analyze the audio signal to produce a score indicating a likelihood that the wakeword is represented in the audio signal. The expression detector then compares the score to a threshold to determine whether the wakeword will be declared as having been spoken.

In some cases, a keyword spotter may use simplified ASR (automatic speech recognition) techniques. For example, an expression detector may use a Hidden Markov Model (HMM) recognizer that performs acoustic modeling of the audio signal and compares the HMM model of the audio signal to one or more reference HMM models that have been created by training for a specific trigger expression. An HMM model represents a word as a series of states. Generally, a portion of an audio signal is analyzed by comparing its HMM model to an HMM model of the trigger expression, yielding a feature score that represents the similarity of the audio signal model to the trigger expression model.

In practice, an HMM recognizer may produce multiple feature scores, corresponding to different features of the HMM models. An expression detector may use a support vector machine (SVM) classifier that receives the one or more feature scores produced by the HMM recognizer. The SVM classifier produces a confidence score indicating the likelihood that an audio signal contains the trigger expression. The confidence score is compared to a confidence threshold to make a final decision regarding whether a particular portion of the audio signal represents an utterance of the trigger expression. Upon declaring that the audio signal represents an utterance of the trigger expression, the content streaming device begins transmitting the audio signal to the remote, network-based speech recognition system for detecting and responding to subsequent user utterances.

In another example, the content streaming device may determine that the voice data does not include a trigger word, and as a result, the voice data is to be processed in a certain manner. For example, voice data without a trigger word may be processed as a search request, such as a search request for media content, as opposed to a verbal query or information request. Depending on whether the voice data is a voice search or a verbal query, the content streaming device may generate different user interfaces, as well as transition from a first set of user interfaces, for example for voice searching, to a second set of user interfaces, for example for verbal queries. For example, user interfaces generated by the content streaming device may include pre-listen information that may include visual and/or audio instructions to a user to provide voice data, visual feedback to indicate that voice data is being detected and/or received, requested information or search results, and other information. Embodiments of the disclosure may generate user interfaces that maintain a look and feel of a user interface theme in transitioning between sets of user interfaces.

Referring to FIG. 1, an overview of an example system 100 in accordance with one or more embodiments of the disclosure is depicted. The system 100 may include a display device 102 in communication with a content streaming device 104. A remote control device 106 may be configured to wirelessly communicate with the content streaming device 104. For example, the remote control device 106 may be connected to the content streaming device 104 or to another device via a Bluetooth, WiFi Direct, and/or other suitable protocol for exchanging information between two devices. In some embodiments, the remote control device 106 may communicate to a cloud or remote server, and the cloud or remote server may determine or identify a computer system or content streaming device that is associated with the remote control device 106 at the time of the communication. For example, the remote server may make a determination based at least in part on proximity or keyword/phrase (e.g., “living room TV”) spoken at the remote control device 106. In certain embodiments, a keyword/phrase can be spoken with a verbal command (e.g., “show weather on living room TV”) or separately (e.g., context from prior interactions, such as “pair with living room TV”).

The content streaming device 104 may be communicatively coupled to the display device 102. For example, the content streaming device 104 may be removably coupled to the display device 102. The display device may be a television, a computer monitor, or any other suitable display device. In certain example embodiments, the display of the display device may be significantly larger in size than the typical display size of a handheld mobile device such as a smartphone or tablet. The content streaming device 104 may be connected to the display device 102 via any suitable interface such as, for example, a Universal Serial Bus (USB) interface, a High-Definition Multimedia Interface (HDMI), or the like.

A user 112 may desire to consume digital content using the content streaming device 104. Content, as used herein, may include any type of content that exists in the form of digital data and which is capable of being consumed. Example types of digital content may include, without limitation, electronic books or other electronic publications, Internet content, audio content, video content, or the like. Content may include text content, graphical content, audio content, video content, or the like, and may include information that is broadcast, streamed, or contained in computer files stored on a device configured to render the content.

The remote control device 106 may include one or more buttons 108 and a microphone button 110 that activates a microphone associated with the remote control device 106. The user 112 may utilize the remote control device 106 to interact with the content streaming device 104. For example, the user 112 may utilize the remote control device 106 to navigate between selectable elements on a user interface presented at the display device 102. The remote control device 106 may be a physical standalone remote control. Alternatively, the remote control device 106 may be a smartphone, tablet, or similar device having a remote control application executing thereon. The remote control device 106 may communicate with the content streaming device 104 using any suitable communication technology or protocol including, but not limited to, Bluetooth, NFC, Wi-Fi Direct, infrared (IR), or the like. The remote control device 106 may include, for example, 5-way cursor controls to enable navigation in four orthogonal directions as well as to enable a selection action equivalent to a tap or click in a touch interface or click interface, respectively. The 5-way cursor controls may be a physical directional pad that includes four directional buttons and a center button or may be provided as part of a touch interface.

In certain example embodiments, when the user 112 selects a particular button of the remote control device 106, a signal may be generated and communicated to the content streaming device 104. Upon receipt of the signal, the content streaming device 104 may generate a first event indicative of a first device operation associated with the selected button. For example, for a selection of a right directional button, the first device operation may correspond to navigation in a direction to the right between user interface representations of content items in a carousel. Buttons may generate different signals based at least in part on a length of time a respective button is held or depressed. For example, the mic button 110 may generate a first signal when the mic button 110 is tapped or pressed for a relatively short length of time, and a second signal when the mic button 110 is pressed and held for a relatively long or predetermined length of time. A tap or press of the mic button 110 may cause the content streaming device 104 to enter a pre-listen state, while a longer press and hold of the mic button 110 may cause the content streaming device 104 to enter a listen state.

In the illustration of FIG. 1, the user 112 may select the mic button 110 by pressing and holding the mic button 110 to indicate a user selection 114 of the mic button. The mic button 110 may generate and send a signal to the content streaming device 104. Upon receiving the signal, the content streaming device 104 may enter a listen state. A listen state may indicate that the content streaming device 104 is monitoring (e.g., at a local receiver or voice server) for voice data. Monitoring may include actively looking for data at one or more receivers or local servers or communication channels. Monitoring may be constant or periodic. The user 112 may communicate voice data 116 to the content streaming device 104 via a microphone of the remote control device 106. For example, while pressing and holding the mic button 110, the user 112 may speak and the microphone of the remote control device 106 may receive analog sound input and generate voice data 116 representative of the analog sound input. The remote control device 106 may send or relay the voice data 116 to the content streaming device 104 over a wireless connection. In some instances, the remote control device 106 may send the voice data 116 to the content streaming device 104 as the voice data is generated and/or as the analog sound input is received.

The content streaming device 104 may receive the voice data 116 from the remote control device 106. While the content streaming device 104 is receiving the voice data 116, the content streaming device 104 may generate a user interface 118 indicating that the content streaming device 104 is receiving voice data, so as to indicate to the user 112 that the voice data is being received. For example, the content streaming device 104 may generate the user interface 118 on a display of the display device 102 with visual feedback, such as an indication of voice modulation as shown in FIG. 1, to indicate to the user 112 that voice data is being received and/or that the content streaming device 104 is in a “listen” state (e.g., that the content streaming device 104 is listening). The user interface 118 may include visual feedback, such as the illustrated voice modulation, that is overlayed on top of previously presented information. For example, the visual feedback may be overlayed on top of a home screen user interface that was previously presented at the display device 102.

Upon receiving the voice data 116, the content streaming device 104 may determine whether the voice data 116 includes a trigger word at determination block 120. In some embodiments, the content streaming device 104 may send the voice data to one or more remote servers for voice processing, while in other embodiments the content streaming device 104 may locally process the voice data 116 to determine whether the voice data includes a trigger word. For example, the content streaming device 104 may send the voice data 116 to one or more remote servers for voice processing. The one or more remote servers may receive the voice data and process the voice data to determine words or phrases included in the voice data, and in some instances, a meaning of the voice data. The one or more remote servers may determine whether the voice data includes a trigger word, and may send an indication of whether the voice data includes a trigger word to the content streaming device 104.

A trigger word may be a word of a set of one or more trigger words that indicates a type of request included in the voice data 116. Example types of requests, as described herein, may include search requests, such as content search requests, verbal queries, such as requests for information, including weather, news, and other information, and the like. Trigger words may be identified by comparing one or more words of the voice data 116 to a table including the set of one or more trigger words. Identification of trigger words may be performed locally at the content streaming device 104 in some embodiments, while in other embodiments, the content streaming device 104 may receive an indication that the voice data 116 included a trigger word, such as from one or more remote servers. In some embodiments, positioning or arrangement of words in the voice data may be used in determining whether the voice data includes a trigger word. For example, in some embodiments, if the first character or word of the voice data is not a trigger word, the voice data may be considered or determined to not include a trigger word.

If it is determined that the voice data 116 includes a trigger word, the content streaming device 104 may generate a first type of user interface 130 at the display device 102. In some embodiments, the content streaming device 104 may receive an indication from the one or more remote servers that indicates the voice data 116 includes a trigger word. Upon receiving the indication from the one or more remote servers, the content streaming device 104 may initiate the first type of user interface 130, which may be associated with a particular user interface theme or user interface mode. In one example, the first user interface type 130 may be associated with a virtual assistant user interface theme. Virtual assistant user interface themes may include a set of one or more cards instead of, or in addition to, a list. Cards may include information that can be presented in succession or upon command. Cards may include information in specific blocks or formatting. The first type of user interface 130 may be based at least in part on a first set of user interfaces that may include certain information, formatting, themes, styles, or other attributes. In some embodiments, the first type of user interface 130 may be selected from a stack or a set of one or more user interfaces. In some embodiments, the first type of user interface 130 may be associated with audio information in addition to visual information. In the example of FIG. 1, presence of a trigger word may indicate that the voice data is a verbal query for information. For example, a verbal query may include a request for information (e.g., news, weather, etc.), a request for certain content, a conversational request which may indicate natural language processing is to be performed on the voice data, and other requests. If the content streaming device 104 determines that the voice data 116 includes a trigger word, the content steaming device 104 may generate a first user interface 132 that may include information related to the verbal query, and may also include an audio response 134. For example, if the user 112 requested local news, the content streaming device 104 may generate the first user interface 132 with information identifying a news source (e.g., NPR), a title (e.g., “Latest NPR Hourly News Update”), and other information. The content streaming device 104 may further initiate the audio response 134 to the verbal query, which may include an audible newscast or audible transcription of news.

If the content streaming device 104 determines that there is or was no trigger word in the voice data 116, the content streaming device 104 may determine that the voice data does not include a verbal request, or that the voice data is a different type of request. In response to the determination, the content streaming device 104 may generate a second type of user interface 140 at the display device 102. The second type of user interface 140 may be a default user interface or may be selected from a second set of user interfaces, and may be associated with a particular user interface theme or user interface mode. In one example, the first user interface type 130 may be associated with a voice search user interface theme. A voice search user interface theme may include a list of one or more options, such as text options or characters that may include titles, names, descriptions, and the like. Lists may be presented at a single user interface, such as a scrollable user interface that lists one or more options. For example, the content streaming device 104 may consider all voice data without a trigger word to be a certain type of request, such as a voice search, and may treat all such voice data accordingly. In FIG. 1, if the content streaming device 104 determines that there was no trigger word in the voice data 116, the content streaming device 104 may consider the voice data to be a voice search and may generate a second user interface 142 in accordance with a voice search. For example, the second user interface 142 may present a set of one or more candidate search options or search strings that are selectable by the user 112 to perform a search, such as a content search. The set of one or more candidate search options may be overlayed on top of a previously presented user interface, as shown in FIG. 1. The user 112 may select one of the presented candidate search options to initiate a content search for the selected search option. In some embodiments, upon receiving the voice data initiation signal from the remote control, the content streaming device 104 may initiate the second type of user interface 140, and then may initiate the first type of user interface 130 upon receiving the indication that the voice data includes a trigger word from the one or more remote servers. In some embodiments, an incoming voice data indication or a voice data initiation signal may be generated by a push-to-talk button at an electronic device and/or a wake word or trigger word preconfigured into an “always-listening” microphone-based device. In such embodiments, detection of the trigger word may result in the voice data initiation signal except when muted, turned off, or otherwise instructed not to listen. For example, “always-listening” devices may include a trigger word unique to device and not the server. Certain embodiments may include two or more trigger words (e.g., first trigger word for device and second trigger word for virtual assistant).

The systems, methods, computer-readable media, techniques, and methodologies for dynamic voice search transitioning may facilitate efficient conveyance of information to users via user interfaces that may include information indicating an operating state of a content streaming device, a processing state of a content streaming device, how voice data is being processed by a content streaming device, and other indications of voice processing. Embodiments of the disclosure may further transition from a first type of user interface for a certain type of voice request to a second type of user interface for a second type of voice request while maintain a look and feel of the user interface.

Example embodiments of the disclosure provide a number of technical features or technical effects. For example, in accordance with example embodiments of the disclosure, certain user interfaces are selected and/or generated in response to certain types of voice requests. For example, a voice search request may trigger presentation of a first type of user interface, while a verbal query may trigger presentation of a second type of user interface. A type of voice data may be determined by the presence of a trigger word in the voice request in some embodiments. The above examples of technical features and/or technical effects of example embodiments of the disclosure are merely illustrative and not exhaustive.

One or more illustrative embodiments of the disclosure have been described above. The above-described embodiments are merely illustrative of the scope of this disclosure and are not intended to be limiting in any way. Accordingly, variations, modifications, and equivalents of embodiments disclosed herein are also within the scope of this disclosure. The above-described embodiments and additional and/or alternative embodiments of the disclosure will be described in detail hereinafter through reference to the accompanying drawings.

Illustrative Process and Use Cases

FIGS. 2-4 depict an example process flow 200 for dynamic voice search transitioning in accordance with one or more embodiments of the disclosure and will be discussed in conjunction with FIGS. 5-12, which depict example user interfaces in accordance with one or more embodiments of the disclosure. Referring first to FIG. 2, FIG. 2 depicts the process flow 200 and a content streaming device 204. The content streaming device 204 may be the same as, or different than, the content streaming device 104 of FIG. 1. While example embodiments of the disclosure may be described in the context of content streaming devices, it should be appreciated that the disclosure is more broadly applicable to any user device configured to generate user interfaces.

The content streaming device 204 may be any computing device with one or more processors and at least one memory communicatively coupled to the one or more processors. The content streaming device 204 may be able to receive and transmit or send information via wired or wireless communication, for example to and from a remote control device, a display device, and/or one or more remote server(s). In some embodiments, the content streaming device 204 may be a media streaming device configured to stream content, such as audio or visual content. In such embodiments, streaming of content may include receiving data packets and, in some instances, storing the data packets in a local buffer. The data packets received may be decoded and output as content for consumption. Accordingly, the content streaming device 204 may begin output of content before receiving an entirety of content data. In some embodiments, the content streaming device 204 may be configured to output streamed media content locally and/or at a connected device. Examples of content streams include, but are not limited to, visual content streaming such as movies, television shows, and other video content, as well as audio content streaming, such as music, audio books, and other audio content.

At block 202 of the process flow 200 in FIG. 2, the content streaming device 204 may receive a pre-listen indication. The content streaming device 204 may receive the pre-listen indication from, for example, a remote control device, a smartphone, a tablet, or another device wirelessly coupled to the content streaming device. In one example, the content streaming device 204 may receive a pre-listen indication from a remote control device. The pre-listen indication may be generated by the remote control device by a tap or a press-and-release of a mic button, or another gesture, of the remote control device. Upon receiving the pre-listen indication, the content streaming device 204 may enter a pre-listen state, in which the content streaming device 204 prepares to listen or monitor for voice data. For example, computer-executable instructions of a listening module(s) 206 stored on a memory of the content streaming device 204 may be executed to initiate a pre-listen state 208. Monitoring for voice data may occur at one or more local receivers or voice servers, for example.

At block 210 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to present pre-listen information at a display device. For example, with reference to FIG. 5, upon receiving the pre-listen indication, the content streaming device 204 may generate a user interface with pre-listen information 310 for presentation at a display device 300. The pre-listen information 310 may include information such as visual or audible user instructions, hints, and the like. For example, the pre-listen information 310 may inform the user how to perform a voice search or a verbal query, or how to send voice data to the content streaming device 204. In some instances, the pre-listen information 310 may include error messages or other indicators of problems or errors with voice data. In the illustration of FIG. 5, the pre-listen information 310 may inform the user that voice data can be sent to the content streaming device 204 by pressing and holding a mic button on the remote control device.

A user may view or consume the pre-listen information 310 and may press and hold a mic button on the remote control device to begin voice data communication with the content streaming device 204. For example, the remote control device may include one or more microphones configured to generate signals based at least in part on incident or ambient sounds. In certain example embodiments, the remote control device may include a microphone configured to receive sound input in the form of analog sound and may generate electrical signals indicative of the analog sound. Processing circuitry of the remote control device may convert the analog sound to digital voice data using an analog-to-digital converter (ADC). The remote control device may utilize the ADC to generate digital voice data from the analog sound input, and may send the voice data to the content streaming device 204 in accordance with a suitable communication protocol including, for example, a local area network (LAN) wireless communication protocol such as WiFi, Wi-Fi Direct, or a personal area network (PAN) such as Bluetooth™, or another wireless communication protocol as described herein.

At block 212, the content streaming device 204 may receive a first voice data initiation indication. For example, upon determining that the user has pressed and held the mic button for a predetermined or threshold length of time, the remote control device may send a voice data initiation indication to the content streaming device 204. The content streaming device 204 may receive the voice initiation indication, which may indicate that voice data transmission will commence, and the content streaming device 204 may enter a listening state in which the content streaming device 204 monitors for voice data. For example, computer-executable instructions of the listening module(s) 206 stored on a memory of the content streaming device 204 may be executed to initiate a listen state 214. The content streaming device 204 may monitor for voice data to be received.

At block 216 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to present visual feedback at a display device. For example, with reference to FIG. 6, the content streaming device 204 may generate a user interface with an onscreen element of visual feedback 320 at the display device 300. The visual feedback 320 may be in the form of voice modulation, as shown in FIG. 6, or any other suitable form to indicate that voice data is being detected and/or received by the content streaming device 204. In some instances, such as voice modulation, the visual feedback 320 may be representative of the voice data as the voice data is being received or detected. In some embodiments, the visual feedback 320 may be overlayed on top of previous user interface, while in other embodiments the visual feedback 320 may be standalone. The visual feedback 320 may include text, graphics, and other indicators to communicate or indicate to the user that voice is being detected and/or voice data is being received, and/or that the content streaming device 204 is listening.

At block 216 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine that voice data is complete. For example, upon release of the mic button on the remote control device, the remote control device may send a signal to the content streaming device 204 an indication that the voice data is complete. In another example, the content streaming device 204 may determine that the voice data is complete after a predetermined length of time has passed and there has been silence or relative silence.

Upon determining that the voice data is complete, the content streaming device 204 may enter a processing state. For example, computer-executable instructions of a voice data module(s) 220 stored on a memory of the content streaming device 204 may be executed to initiate a processing state 222. In the processing state 222, the content streaming device 204 may process the voice data to determine a meaning of the voice data. In some embodiments, the content streaming voice 204 may process the voice data locally, while in other embodiments, the content streaming device 204 may send the voice data to one or more remote servers for processing. Processing may include natural language processing (or other speech recognition processing) on the voice data to determine a meaning of the corresponding sound input detected by the microphone. Processing the voice data may include generating speech-to-text translations of the data. In some embodiments, transmission of the voice data by the content streaming device 204 may begin when initial voice data is received by the content streaming device 204, before an entirety of the voice data is received. In such embodiments, processing time at the one or more remotes servers may be reduced.

At determination block 224 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine whether the voice data is understood. The determination of whether the voice data is understood may be based at least in part on the results of the processing of the voice data. If the results of the processing indicate that the voice data was not deciphered, a determination may be made that the voice data is not understood. If the results of the processing indicate that the voice data is deciphered, a determination may be made that the voice data is understood.

If it is determined that the voice data was not understood, the process flow 200 may continue to block 226 at which user assistance information is presented at the display device. For example, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to generate a user interface with user assistance information for presentation at the display device. In some instances, the user assistance information may be presented at the same or at a user interface similar to the user interface with the pre-listen information (such as that shown in FIG. 5), with an error message or other indication that the voice data was not understood. The user interface may further include detailed user assistance information, such as how long to hold down the mic button for, instructions to speak louder or more clearly, and the like. Upon presenting the user assistance information, the content streaming device 204 may return to the pre-listen state at block 228 and may await voice data or a voice data initiation indication.

If it is determined that the voice data was understood at determination block 224, the process flow 200 may continue to determination block 230. At determination block 230, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine whether the voice data includes a trigger word. A trigger word may be a word, character, or sound that indicates how particular voice data is to be processed. For example, a trigger word may indicate that voice data is a verbal query and/or should be processed as conversational data instead of a content search. In addition, depending on how voice data is processed, the content streaming device 204 may generate different user interfaces. For example, a first set of user interfaces may be generated for verbal queries or conversational requests, while a second set of user interfaces may be generated for voice searches. In some embodiments, trigger words may be found at certain instances of the voice data, such as at a first word, a last word, or at another position within the voice data. The determination of whether the voice data includes a trigger word may be made at the content streaming device 204 or at a remote server, which may send an indication of whether the voice data includes a trigger word to the content streaming device 204. In one example, some or all of the words in the voice data may be compared to a table of a set of one or more trigger words to determine whether the voice data includes a trigger word.

If it is determined that the voice data includes a trigger word, the process flow 200 may continue to FIG. 3. If it is determined that the voice data does not include a trigger word, the process flow may continue to FIG. 4. Referring first to FIG. 3, at block 232, the content streaming device 204 may determine that a trigger word was used. Upon determining that the voice data includes a trigger word, the content streaming device 204 may initiate a first set of user interfaces. For example, computer-executable instructions of a card selection module(s) 234 stored on a memory of the content streaming device 204 may be executed to initiate one or more conversation card(s) presented with a conversation UI theme 236. Conversation cards may be user interfaces generated in response to conversational requests or verbal queries from a user and may be different than other user interfaces such as, for example, voice search user interfaces. In some embodiments, cards may be implemented using a template-based data structure in which a remote server (e.g., a cloud server, etc.) sends data to fill a template of the card with an indication of a particular template to use. Templates may be selected from any number of templates, and a receiving device may generate the card with the particular template. The generated card may be filled with data and presented for consumption in some embodiments.

At block 238 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine a response to the voice data, or to receive response information (e.g., from one or more remote servers). For example, upon processing of the voice data, the content streaming device 204 may determine that the voice data includes a verbal query or request for information related to news, traffic, weather, or other information, a request to perform an action (e.g., play a song, etc.) and in response, the content streaming device 204 may determine the requested information and/or determine an appropriate response. In some embodiments, the content streaming device 204 may determine responses to voice data locally, while in other embodiments the content streaming device 204 may receive an indication of responses from one or more remote servers.

At block 240 of the process flow 200, response information may be sent to a display for presentation with the conversation UI theme. For example, with reference to FIG. 7, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine first information in response to the first verbal request of the first voice data and to generate a first user interface or first conversation card 330 for presentation at the display device 300. The first conversation card 330 may be a user interface that communicates to the user that the voice data was processed as a verbal query and may present information relevant to the verbal query. For example, the first conversation card 330 may include a description of audio that is being presented to a user, title or author information, and other information. User interfaces generated by the content streaming device 204, such as conversation cards and/or voice search cards, may include various selectable onscreen elements such as buttons, icons, menus, and so forth. Depending on the verbal query or meaning of the voice data, the content streaming device 204 may further initiate a first audio response 340 at, for example, a speaker of the display device 300 in addition to the first conversation card 330. The first audio response 340 may be presented at a different speaker that is remote from the display device 300 in some embodiments. Some responses may not include an audio component. In the example of FIG. 7, the content streaming device 204 may begin an audio newscast and may present related information that may describe the audio on the user interface or first conversation card 330 presented at the display device 300.

In some instances, while the first conversation card 330 and/or the first audio response 340 is being presented, a user may interrupt the content streaming device 204 with a subsequent request or with additional voice data. For example, while listening to the newscast in FIG. 7, the user may desire to be presented with weather information and may interrupt the presentation of the newscast.

In such instances, at block 242 of the process flow 200 in FIG. 3, the content streaming device 204 may receive a second voice data initiation indication, which may be during presentation of the first audio 340. For example, the user may press and hold a mic button on a remote control to send a voice data initiation indication to the content streaming device 204. The content streaming device 204 may receive the second voice data initiation indication and at block 244 of the process flow 200, the content streaming device 204 may pause or cancel the first audio response that is being presented.

At block 246 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to present visual feedback over the first conversation card at the display device. For example, with reference to FIG. 8, the content streaming device 204 may generate a user interface with an onscreen element of visual feedback 350 at the display device 300. The visual feedback 350 may be in the form of voice modulation, as shown in FIG. 8, or any other suitable form to indicate that voice data is being detected and/or received by the content streaming device 204. In some instances, such as voice modulation, the visual feedback 350 may be representative of the voice data as the voice data is being received or detected. In some embodiments, the visual feedback 350 may be overlayed on top of previous user interface, or the first conversation card 330 in the example of FIG. 8. The visual feedback 350 may include text, graphics, and other indicators to communicate or indicate to the user that voice is being detected and/or voice data is being received, and/or that the content streaming device 350 is listening. The first conversation card 330 may persist or remain presented in the background while the second voice data is being received and/or while the visual feedback 350 is being presented such that if the second voice data includes an interaction command with an interaction element of the first conversation card 330 (e.g., a selection of a particular selectable onscreen element of the first conversation card 330, etc.), or another multi-term interaction with the first conversation card 330, the first conversation card 330 is readily available. The content streaming device 204 may determine that the conversation card user interface type, or user interface theme was the last used user interface theme, and may initiate the conversation card user interface theme.

Upon completion of the voice data, the process flow 200 may proceed to determination block 248 to determine how the second voice data is to be processed. At determination block 248, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may again be executed to determine whether the voice data includes a trigger word. If it is determined that the second voice data includes a trigger word, the process flow 200 may continue to block 250. If it is determined that the second voice data does not include a trigger word, the process flow may continue to FIG. 4.

In the event it is determined that the second voice data includes a trigger word, the process flow 200 may continue to block 250. The content streaming device 204 may determine, for example via voice processing, a request associated with the second voice data, and at block 250, the content streaming device 204 may determine a response to the second voice data. Upon determining a response to the second voice data, the process flow 200 may continue to block 252, at which the content streaming device 204 may present a second audio response and/or a second user interface. For example, with reference to FIG. 9, the user may interrupt the newscast with a verbal query for weather information. In response, the content streaming device 204 may determine weather information and may present a user interface or a second conversation card 360 with weather information at the display device 300. In some embodiments, where a second audio response is appropriate (e.g., audible version of weather information, etc.), the content streaming device 204 may initiate a second audio response 370 at the display device 300 or at another speaker. For example, the weather forecast may be presented as part of the second audio response 370.

Upon presenting some or all of the second audio response and/or the second user interface, the process flow 200 may optionally return to, or regenerate, the first conversation card and/or first audio. For example, after presenting some or all of the weather information, or after presenting some or all of the weather information for a predetermined length of time, the content streaming device 204 may return to the first conversation card 330 of FIG. 7 and/or may resume the audible newscast of the first audio response 340. Alternately, in some instances, such as an instance where a first media content, such as a first movie, is being presented and is interrupted with a request for a second media content, or a different movie, presentation of the first media content and/or first audio may be canceled instead of or in addition to pausing the first audio response.

Referring now to FIG. 4, if it is determined at determination block 230 or at determination block 248 that the voice data does not include a trigger word, the process flow 200 may continue to FIG. 4. In certain embodiments, if voice data does not include a trigger word, the voice data may be processed as a default voice request, which may be a voice search. For example, a user may use a voice-based search function to search for content. The voice-based search function may be initiated at a remote control device by pressing and holding the mic button, for example.

If it is determined at determination block 230 or 248 that the voice data does not include a trigger word, the process flow 200 may continue to FIG. 4. At block 256 of the process flow 200 in FIG. 4, the content streaming device 204 may determine that the voice data did not include a trigger word. Upon determining that the voice data did not include a trigger word, the content streaming device 204 may initiate a second set of user interfaces. For example, computer-executable instructions of the card selection module(s) 234 stored on a memory of the content streaming device 204 may be executed to initiate one or more voice search card(s) presented with a voice search UI theme 258. Voice search cards may be user interfaces generated in response to voice-based search requests, such as requests for content, from a user and may be different than other user interfaces such as, for example, conversation cards or user interfaces.

At block 260 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine candidate search options for presentation. For example, the content streaming device 204 may determine a set of candidate search strings based at least in part on the second voice data. In some embodiments, the content streaming device 204 may determine the set of candidate search strings locally, while in other embodiments the content streaming device 204 may send the second voice data to a remote server for processing of the second voice data, and may receive a set of candidate search strings from the remote server identified from the processing of the second voice data. The candidate search options or search strings may provide search terms in the form of text, graphics, and the like for use in a content search.

At block 262 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to present the candidate search queries. For example, with reference to FIG. 10, the content streaming device 204 may present a user interface of a first voice search card 380 at the display device 300. The first voice search card 380 may include candidate search queries or options 390, and in some embodiments, a text search option 450. The candidate search options 390 may include one or more selectable search options that, when selected, initiate a content search for the selected option. The text search option 450 may cause a text searching user interface to be presented that may facilitate text based searching for content. While this example relates to text searching, other embodiments of the disclosure may include voice dictation themes, such as speech-to-text applications, or mobile application-specific themes, such as voice commands in a calendar or map application. In such embodiments, a default theme may be used until a virtual assistant trigger word is detected.

In FIG. 10, the content streaming device 204 may present information associated with the set of candidate search options 390 at the display device 300. For example, the candidate search options 390 may include “mad men,” “madman,” and “madmun,” and may be based at least in part on the second voice data. The candidate search options 390 may be presented as text, graphics, or in other digital forms. A user may select one of the presented search options 390 to initiate a content search for the selected search option. For example, the user may select one of the candidate search options 390 via a remote control device 400. The remote control device 400 may have a selection wheel or input 410 that the user may use to input a user selection 420 for one of the candidate search options 390.

At block 264 of the process flow 200 in FIG. 4, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to determine a selection of a candidate search option for searching. For example, the user may select “mad men” in the candidate search options 390 via the remote control device 400 in FIG. 10. The content streaming device 204 may receive an indication of a selection of a selected candidate search string or candidate search option. In some embodiments, the content streaming device 204 may send the selected candidate search string to a remote server for content searching to identify content relevant to the selected candidate search string, while in other embodiments, the content streaming device 204 may perform content searching.

In certain embodiments, the content streaming device 204 may receive a set of search results that may include content selection options based at least in part on the selected search option. In other embodiments, the content streaming device 204 may determine search results, that may include content selection options, in response to the selected candidate search option. Metadata associated with the content selection options (e.g., title, plot summary, etc.) may be communicated to or determined by the content streaming device 204, which may direct presentation of the metadata via the display device 300.

At block 266 of the process flow 200, computer-executable instructions of one or more module(s) stored on a memory of the content streaming device 204 may be executed to present search results at the display device. For example, with reference to FIG. 11, the content streaming device 204 may present a user interface of a search result user interface 430 at the display device 300 with search results 440. The search results 440 may be selectable content options determined in response to the second voice data. For example, the search results 440 may include cover art and other metadata associated with one or more content selection options. The user may select one of the content selection options to begin consumption of the selected content option. The search results 440 and/or content selection options identified as part of the voice-based searching functionality described herein may include one or more content items (e.g., movies) identified as having a threshold level of relevance to the processed voice data (e.g., a speech-to-text translation of the data).

In some instances, the search results 440 may be different than what a user wanted, or a user may decide to conduct another search after viewing the search results 440. For example, in FIG. 11, the user may select the text search option 450. The text search option 450 may be selected as an onscreen element as part of the search result user interface 430, and/or may be associated with a physical or virtual button at the remote control device 400.

In FIG. 12, upon selecting the text search option 450, the content streaming device 204 may generate a user interface with a third voice search card 480 at the display device 300. The third voice search card 480 may include a text input interface 490 configured to receive input from a user for text. For example, a user may use the remote control device 400 to navigate the text input interface 490 and select one or more characters in order to input a text based search. Upon completion of user input, the content streaming device 204 may initiate a content search based at least in part on the textual input by the user at the text input interface 490.
